Embodiment Construction

[0013] The present invention will be further described below with reference to the drawings and embodiments.

[0014] Such as figure 1 Shown: a methanol recovery processing system, the recovery processing system includes a preheater 1, a recovery tower 2, a reboiler 3, and a condenser 4. The recovery tower 2 is connected to the preheater 1, reboiler 3 through pipelines, respectively It is connected with condenser 4, where the raw materials are preheated from preheater 1 and then sent to recovery tower 2, after being processed by recovery tower 2, they are sent to reboiler 3 to obtain methanol-containing steam, and then through recovery tower 2 after recovery treatment It is sent to the condenser 4 for condensation to obtain the recovered methanol. Specifically, the reboiler 3 communicates with the lower and bottom of the recovery tower 2 through pipelines, so that the recovery tower 2 transmits the initially processed raw materials to the reboiler 3 through the pipeline at the b...

Abstract

The invention discloses a methanol recovery treatment system which is characterized by comprising a preheater (1), a recovery tower (2), a reboiler (3) and a condenser (4), wherein the recovery tower (2) is respectively communicated with the preheater (1), reboiler (3) and condenser (4) through a pipeline; and the raw material is preheated by the preheater (1), delivered to the recovery tower (2), treated by the recovery tower (2) and delivered to the reboiler (3) to obtain methanol-containing steam, and the methanol-containing steam is recovered by the recovery tower (2), sent to the condenser (4) and condensed to obtain the recovered methanol. The raw material is subjected to circular treatment between the recovery tower and reboiler, so that the methanol in the raw material is sufficiently recovered, and part of heat generated by the reboiler is transferred to the preheater for reutilization via the recovery tower. The system has the characteristics of low cost, high efficiency and higher energy utilization efficiency, and is suitable for popularization and application.

Description

Technical field [0001] The invention relates to a methanol recovery processing system. Background technique [0002] In the paint industry, the used waste contains a certain amount of methanol. Due to the lack of low-cost and high-efficiency recycling equipment, this part of methanol is generally discarded, which is not conducive to the construction of an environmentally-saving society. Summary of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art and provide a methanol recovery and treatment system that can recycle energy, reduce costs and have higher efficiency. [0004] The purpose of the present invention is solved by the following technical solutions: [0005] A methanol recovery processing system, characterized in that: the recovery processing system includes a preheater, a recovery tower, a reboiler and a condenser, and the recovery tower is connected to the preheater, reboiler and condenser through pipelines. The r...
